h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

I went to the hairdresser last thursday and now feels hateful towards hairdressers (or at least the one who dressed my hair) and ask myself a thousands questions :

What on earth did I do to this women to make her having such a revenge on my hair? I can swear I was polite and kind so why did she cut my hair in such an horrible way ??

Why do hairdresser understand "cut as much as you want" when you say "I don't want to have short hair", and "make it as ugly as you can, I don't care" instead of "I'm not sure, maybe you can advice me"?

Why did she ask me the permission to cut a centimeter on a wisp of hair after having cut at least 1 kg hair without permission ?

Do the fact of saying "hum, isn't it a bit messy?" when I thought "I look like having survived a plane crash!" make me an hypocrite person?

Well I'd had a lot more to ask about hairdressers pent-up aggressiv tendancies, but it would be boring and I guess there are more tragic issues than uggly hair cuts (at least, like a friend of mine told me, now if the bus driver laughs when I come in, I'll know why...)
